Nature evolves biological molecules such as proteins through iterated rounds of diversification, selection, and amplification. The present invention provides methods, compositions, and systems for syntheiszing, selecting, amplifying, and evolving non-natural molecules based on nucleic acid templates. The sequence of a nucleic acid template is used to direct the synthesis of non-natural molecules such as unnatural polymers and small molecules. Using this method combinatorial libraries of these molecules can be prepared and screened. Upon selection of a molecule, its encoding nucleic acid template may be amplified and/or evolved to yield the same molecule of the present invention allow for the amplification and evolution of non-natural molecules in a manner analogous to the amplification of natural biopolymer such as polynucleotides and protein.
大自然通过一轮又一轮的多样化、选择和扩增,使蛋白质等生物分子不断进化。本发明提供了基于核酸模板合成、选择、扩增和进化非天然分子的方法、组合物和系统。核酸模板的序列用于指导非天然分子(如非天然聚合物和小分子)的合成。利用这种方法可以制备和筛选这些分子的组合文库。在筛选出分子后,可对其编码核酸模板进行扩增和/或进化,以产生与本发明相同的分子,从而以类似于扩增多核苷酸和蛋白质等天然生物聚合物的方式扩增和进化非天然分子。
